So your stance is that second hand smoke is already regulated to the point it needs to be, but it kills nearly 4x as many innocent people as all gun homicides, police shootings, and accidents combined. So then if you're willing to accept that, then I can't find good reason to argue for every more restrictions on guns. You brush off alcohol, but drunk driving deaths are a very real killer, quite literally thousands of people. Guns are already more than reasonably regulated when weighed against other freedoms and rights and their cost to society.
No, I challenge the "conventional wisdom" about second hand smoke because the actual research doesn't back it. There is a difference between what research shows and how this information is filtered to the public. What we are told in articles we often read is that there is a high risk. Often large numbers are cited. These results are often outliers. Public health officials and organizations (both gov and NGO's) will often exaggerate risks because they think there is no harm in doing so, that it's actually a benefit to err on the side of alarmism.

The only category of exposure that showed a trend toward increased risk was living in the same house with a smoker for 30 years or more.

One thing that is important to understand is that studies on second hand smoke generally evaluate non-smokers who are married to smokers. Occasionally they may track people who get daily exposure in a work place. They rarely track people who get transitory or occasional exposure in public places because it is impossible to quantify exposure from one subject to the next. Notice that the above cohort study tracked all categories. It found risk only with long term daily indoor exposure.
Whatever the total number of deaths per year from second hand smoke, there is no evidence whatsoever that anyone is dying from occasional exposure, and accordingly, there is little to no public health justification for smoking bans in public places. Work places make sense. Not many other situations, and certainly not these outdoor smoking bans that are starting to pop up in various places.
What would you suggest we do aside from what we're already doing in relation to second hand smoke? Once you've banned it in every indoor location besides one's own home or in one's own car, the only thing left is to ban cigarettes entirely. In New York they've almost done that already by taxing it so much that no one who isn't wealthy can afford a smoking habit. This, in turn, has created an enormous illegal cigarette trade in NY which, like all forms of prohibition, has resulted in unpleasant side effects, including some murders. Perhaps you're not seeing people starting threads about banning cigarettes, which is the only next logical step that we haven't yet tried, because we've seen the results of alcohol and drug prohibition, namely that they don't work very well and cause more problems than they solve.
So far as drunk driving, I don't brush it off. But it's already illegal, isn't it? The parallel here would be that guns should be illegal as well, right? Are you suggesting that we should all be for substantially increasing the penalties for drunk driving, like treating it as a felony on a first offense? I see no inconsistency between not supporting draconian penalties for first offense drunk driving and supporting some gun control.
